Abstract (en)
[origin: EP0315238A2] Bi-oriented, heat-sealable and heat-shrinking films having good optical and mechanical characteristics, are obtained by means of extrusion and bi-axial stretching of a mixture of ethylene and alpha -olephin copolymers containing: a) from 95 to 99.9% by weight of ethylene/octene-1 copolymer; and b) from 5 to 0.1% by weight of an ethylene/butene-1 or ethylene/hexene-1 copolymer; with said copolymers having a density value comprised within the range of from 0.900 to 0.940 g/cc.
